Abstract

Generators with inductive energy storage units and semiconductor opening switches designed for laser excitation are described. Operation of the generators on a gas-discharge load is considered and possible excitation modes are discussed. A longitudinal N₂ laser, transverse discharge nonchain HF laser, and CO₂ laser are developed based on this pumping technique. Output energies of 0.6 J and 3.2 J and laser efficiencies of 5.5% and over 17% were demonstrated on H ₂-SF₆ and He-CO₂-N₂ gas mixtures, respectively. High laser parameters obtained demonstrate the considerable promise of such inductive generators for pumping different gas lasers
